Because Invisalign Matthews uses clear plastic aligners to position and straighten teeth, you can keep your active lifestyle during treatment. Unlike braces, Invisalign aligners have no metal bands or wires to irritate your mouth. So go ahead and be as active as you like. Since Invisalign is removable, just take the clear aligners out for special events or if you’re going to indulge in a sticky, gooey snack.
